尽管石墨烯由于巨大的离域π电子系统而在化学上极其惰性，但人们已经开发了各种方法来实现其有效的化学修饰。共价化学可有效调节石墨烯的物理性质。通过将 sp(2) 杂化碳原子转化为 sp(3) 碳原子，可以从石墨烯支架构建出具有超越母体石墨烯的迷人特征的新型二维 (2D) 材料和二维超晶格，从而极大地扩展了石墨烯家族及其吸引力。在这个视角中，从定制石墨烯的能带结构以及创建新的二维材料和二维超晶格的角度展示了共价化学的力量。特别关注共价石墨烯化学对电子器件和材料科学的一般考虑和理解。
Although graphene is extremely inert in chemistry because of the giant delocalized pi electron system, various methods have been developed to achieve its efficient chemical modification. Covalent chemistry is effective to modulate the physical properties of graphene. By converting the sp(2) hybridized carbon atoms to sp(3) ones, new two-dimensional (2D) materials and 2D superlattices with fascinating features beyond mother graphene could be built from the graphene scaffold, greatly expanding the graphene family and its attraction. In this Perspective, the power of covalent chemistry is demonstrated from the viewpoint of tailoring graphene's energy band structure as well as creating new 2D materials and 2D superlattices. A specific focus is laid on the general consideration and understanding of covalent graphene chemistry toward electronic devices and material science.
